| The modules described in this chapter implement various algorithms of |
| a cryptographic nature. They are available at the discretion of the |
| installation. Here's an overview: |
| |
| \begin{description} |
| |
| \item[md5] |
| --- RSA's MD5 message digest algorithm. |
| |
| \item[mpz] |
| --- Interface to the GNU MP library for arbitrary precision arithmetic. |
| |
| \item[rotor] |
| --- Enigma-like encryption and decryption. |
| |
| \end{description} |
| |
| Hardcore cypherpunks will probably find the cryptographic modules |
| written by Andrew Kuchling of further interest; the package adds |
| built-in modules for DES and IDEA encryption, provides a Python module |
| for reading and decrypting PGP files, and then some. These modules |
| are not distributed with Python but available separately. See the URL |
| \url{http://www.magnet.com/\~amk/python/pct.html} or send email to |
| \email{amk@magnet.com} for more information. |
